Abstract | Bruchid beetles (Callosobruchus maculatus) and mungbean yellow mosaic virus (MYMV) disease are the two major causes of yield constraints in blackgram. Marker-assisted selection was performed among a population developed from the cross combinations of MDU 1 (susceptible female parent) and the TU 68 (resistant male parent) to select for bruchid and MYMV disease resistance. The selected introgression lines (ILs) were significantly superior for bruchid and MYMV disease resistance traits. The introgression lines namely IL-9-1, IL-12-1, IL-12-2, IL-12-7, IL-12-9 and IL-12-10 recorded higher seed yield during the disease prevalent environment than the female parent MDU 1. But the yield performances were lower than the female parent MDU 1 in the disease-free environment. The reduced performance for yield might be due to the linkage drag among the introgression lines. Hence, the linkage drag can be eliminated by the backcross breeding method. However, the successful selection for dual biotic resistance was achieved among the introgression lines. Further, better recombinants must be isolated to obtain good yielding variety and bruchid and MYMV disease resistance. |
